A fuzzy die that has a weight of 1.70N hangs from the ceiling of a car by a massless string. The car travels on a horizontal road and has an acceleration of 2.70m/s^2 to the left. The string makes an angle theta with respect to the vertical, as shown in the figure below. 1) What is the angle theta?

A fuzzy die that has a weight of 170N hangs from the ceiling of a car by a massless string The car travels on a horizontal road and has an acceleration of 270ms class=

Respuesta :

First we calculate the mass of the fuzzy die

[tex]m=\frac{W}{g}[/tex]

m is the mass, W is the weight, and g is the gravity

m=?

W=1.70N

g=9.8 m/s^2

we susbtitute

[tex]m=\frac{1.70}{9.80}=0.17\text{ kg}[/tex]

Then we calculate the force of x

[tex]Fx=0.17(2.70)=0.468\text{ N}[/tex][tex]Fy=1.70N[/tex]

Then we have the next diagram

Therefore for the angle

[tex]\theta=\arctan (\frac{F_x}{F_y})=arctan(\frac{0.468}{1.70})=15.4\text{ \degree}[/tex]

ANSWER

The angle is 15.4°
